Title: Improvements in vehicle sanding appliances
IPC: B60B39/10
Filed: 1932-12-05
Abstract: 399,046. Vehicle sanding-apparatus. DEMAG AKT.-GES., 64, Werthauserstrasse, Duisburg, Germany. Dec. 5, 1932, No. 34456. Convention date, Dec. 4, 1931. [Class 103 (iii).] A conical cup 8 closing the sandcontainer 1 of a vehicle sanding appliance is secured to a rod 3 supported by a diaphragm 2 fixed at its periphery inside the container, the upper end of the rod 3 being struck repeatedly to raise and lower the cup 8 and thus release sand, by the core 5 of an electromagnetic device, While the device is energized by depression of a switch 9. As the core moves upwards it breaks the electric circuit by raising a contact arm 7 and then falls under gravity to strike the rod 3, the arm 7 also dropping to close the circuit and thus cause repetition of the operation. The sand is thrown by the cup 8 against the outside of the container and thence descends through a funnel to the wheel track. The cup 8 may have upwardly extending projections to strike the container to cause it to vibrate. Instead of the make-and-break device an A.C. solenoid may be used, the vibrator of its core being caused by the periodicity of its current.

Abstract: For strand guiding, rollers (1) or rolls have, distributed over their longitudinal extent, a plurality of bearing pins (2, 2') which are mounted in bearing housings (3, 3'). In order to move all the bearing housings (3, 3') of a roller (1) or roll, with the aid of the two bearing housings (3') arranged at the ends of the rollers or rolls, into the position necessary for installation and to keep them in this position, so that manipulation at the barely accessible, internally located bearing houses (3) during installation is no longer necessary, the bearing housings (3, 3') of a roller (1) or roll are connected to one another by axially parallel pipelines (6) for the purpose of preventing mutual twisting about the roller or roll axis. <IMAGE>

The pour point of a liquid is measured by cooling a sample 2 of the liquid in a container 1 starting at a temperature higher than the temperature to be determined and using a coolant jacket 5, the container being slowly and continuously rotated about its centre line on a base 3, a sphere 6 located on a rigid arm 7 pivoted on a shaft 8 being immersed in the liquid sample, so that as the container 1 rotates the sphere deviates from its equilibrium position to an extent dependent on the viscosity of the liquid, this deviation increasing rapidly at the pour point and being detected by equipment located in a box 9 which monitors the position of the upper end of the arm 7, the temperature at this point being measured using a thermocouple located on the sphere 6. The position of the arm 7 and the temperature are preferably recorded. In an alternative embodiment the container is periodically tilted instead of being rotated and the sphere 6 is replaced by a flat plate which is moved by the liquid as the container tilts.

Title: Quadraphonic sound transmission or recording system
IPC: H04S3/02
Filed: 1972-07-28
Abstract: 1414166 Quadraphonic systems BRITISH BROADCASTING CORP 4 July 1973 [28 July 1972] 35467/72 Heading H4R A quadraphonic system operates with a three channel transmission signal, one of the signals being an omnidirection sum signal and the other two signals being signals dependent on the position of a sound source with repect to respective different axes. The signals may be derived from two pairs of microphones, each microphone having a cardioid directional characteristic Fig. 2, with the sum signals from each pair providing the omnidirection signal, either by taking one only of the sum signals, or by averaging the sum signals, the other two signals being derived from the difference of the signals of the microphones in each pair. Alternatively a single omnidirectional microphone can provide the omnidirectional sum signal and two microphones having "figure of eight" characteristics with the axes at right angles, one to the other, can provide the other two signals. For reproduction the omnidirectional signal is combined with each of the other signals in sum and difference to provide four output signals. For transmission by broadcast the two difference signals can modulate quadrature carriers transmitted with the sum signal to provide a signal which is compatible with the conventional stereo broadcasts. On reproduction the ratio of the sum to the difference signal can be modified to vary the apparent sound stage size.

Title: Process for the oxidation of a saturated hydrocarbon to a mixture containing the corresponding alcohol
Inventor: ALAGY JACOB
IPC: C07C45/33
Filed: 1965-08-18
Abstract: Oxidation of a saturated hydrocarbon in the liquid phase to a mixture containing the corresponding alcohol by reacting the hydrocarbon with gases containing molecular oxygen in an oxidation zone (1), condensing the gaseous effluent (4) from the oxidation reactor in an air or water condenser (8) and separating oxygen-poor gases and liquid unconverted hydrocarbon in a separator (10), contacting at least a part of the oxygen-poor gases outside the oxidation zone in an exchanger (13) in direct heat exchange with at least part of the condensate of unconverted hydrocarbons previously brought to a higher temperature (e.g. no more than 50 DEG  in excess of the oxidation temperature) than the reaction temperature in the oxidation zone preferably by direct or indirect heat exchange under reflux with hot gaseous effluent from the oxidation zone using a second exchanger (5), and recycling the mixture of unconverted gases so formed into the oxidation zone. Preferably fresh hydrocarbons to be oxidized are added to the condensate of unconverted hydrocarbons at a suitable point in the apparatus (e.g. to the separator 10) before the condensate comes into direct heat exchange with the oxygen-poor recycled gases. The preferred hydrocarbon is cyclohexane and in this case the oxygen-poor gases are cooled to less than 20 DEG  C. before being contacted with the hot condensate of unconverted hydrocarbons.
